Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A maliciously crafted PDF file when parsed through Autodesk AutoCAD 2023 causes an unhandled exception. An attacker can leverage this vulnerability to cause a crash or read sensitive data or execute arbitrary code in the context of the current process.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

A maliciously crafted PDF file parsed by Autodesk AutoCAD 2023 triggers an unhandled exception that can lead to arbitrary code execution in the current process context. The vulnerability stems from improper handling of malformed PDF structures during the parsing process.

MitigationApply the vendor patch for AutoCAD 2023 when available; until then, avoid opening untrusted or unexpected PDF files in AutoCAD and disable PDF integration if not required.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed AutoCAD product
    Open AutoCAD and go to Help > About Autodesk AutoCAD, or run the app and check the title bar/splash screen for the product name (e.g., AutoCAD, AutoCAD Architecture, AutoCAD Civil 3D, etc.)
    Affected if Any of the following products are installed: AutoCAD, AutoCAD Advance Steel, AutoCAD Architecture, AutoCAD Civil 3D, AutoCAD Electrical, AutoCAD LT, AutoCAD Map 3D, or AutoCAD Mechanical
  2. Check installed version number
    Run the VER command in AutoCAD, or look at the version info in Help > About AutoCAD. Note the full version number (e.g., 2022.0, 2022.1.2, 2023.0, 2023.1.0)
    Affected if Version is 2022.x where x is less than 1.3, OR version is 2023.x where x is less than 1.1 (i.e., versions 2022.0 through 2022.1.2, or 2023.0 through 2023.1.0)
  3. Confirm PDF integration is in use
    Check if PDF import/export or PDF underlay features are enabled by typing PDFATTACH or PDFIMPORT at the AutoCAD command prompt. If these commands are available, PDF integration is present
    Affected if PDFATTACH or PDFIMPORT commands are functional and available in the installation

The environment is affected if an AutoCAD variant (2022.x before 1.3 or 2023.x before 1.1) is installed with PDF integration features enabled and the user opens a malicious PDF file.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to 2022.1.3 / 2023.1.1 or later
Fixed in 2022.1.32023.1.1
Interim mitigation

Apply the vendor patch for AutoCAD 2023 when available; until then, avoid opening untrusted or unexpected PDF files in AutoCAD and disable PDF integration if not required.

Recommended fix High confidence

AutoCAD 2022.1.3 or later; AutoCAD 2023.1.1 or later (and corresponding versions for AutoCAD variants)

  1. 1. Close any running AutoCAD instances
  2. 2. Ensure you have a backup of your work and settings
  3. 3. For AutoCAD 2022.x: Upgrade to version 2022.1.3 or later
  4. 4. For AutoCAD 2023.x: Upgrade to version 2023.1.1 or later
  5. 5. Download the appropriate update from the Autodesk Account portal or use the Autodesk Access application
  6. 6. Run the installer with administrator privileges
  7. 7. Follow the on-screen installation prompts
  8. 8. Restart AutoCAD after the update completes
Caveat Standard Autodesk update considerations apply - some older drawing features or third-party plugins may require updates for compatibility with newer versions
